This package provides a GLR parser generator for OCaml. It is able to generate self-extensible parsers (also called adaptive parsers) as well as extensible lexers for the parsers it produces.

Dune-configurator is a small library that helps writing OCaml scripts that test features available on the system, in order to generate config.h files for instance. Among other things, dune-configurator allows one to:

• test if a C program compiles

• query pkg-config

• import #define from OCaml header files

• generate config.h file

Merlin is an editor service that provides modern IDE features for OCaml. Emacs and Vim support is provided out-of-the-box. External contributors added support for Visual Studio Code, Sublime Text and Atom.

This package provides two library modules:

• Stream: imperative streams, with in-place update and memoization of the latest element produced.

• Genlex: a small parameterized lexical analyzer producing streams of tokens from streams of characters.

The two modules are designed for use with Camlp4 and Camlp5: The stream patterns and stream expressions of Camlp4/Camlp5 consume and produce data of type 'a Stream.t. The Genlex tokenizer can be used as a simple lexical analyzer for Camlp4/Camlp5-generated parsers.

The Stream module can also be used by hand-written recursive-descent parsers, but is not very convenient for this purpose.

The Stream and Genlex modules have been part of the OCaml standard library for a long time, and have been distributed as part of the core OCaml system. They will be removed from the OCaml standard library at some future point, but will be maintained and distributed separately in the camlpstreams package.

Astring exposes an alternative String module for OCaml. This module balances minimality and expressiveness for basic, index-free, string processing and provides types and functions for substrings, string sets and string maps. The String module exposed by Astring has exception safe functions, removes deprecated and rarely used functions, alters some signatures and names, adds a few missing functions and fully exploits OCaml's newfound string immutability.

Extensions to printf-style format-strings for user-defined string conversion.

Stdio implements simple input/output functionalities for OCaml. It re-exports the input/output functions of the OCaml standard libraries using a more consistent API.

This package is a no-op ppx rewriter. It is used as a lint tool to enforce some coding conventions across all Jane Street packages.

BINSEC is a binary analysis platform which implements analysis techniques such as symbolic execution. The goal of BINSEC is to improve software security at the binary level through binary analysis. BINSEC is a research tool which relies on prior work in binary code analysis at the intersection of formal methods, program analysis security and software engineering.

Dune is a build system for OCaml. It provides a consistent experience and takes care of the low-level details of OCaml compilation. Descriptions of projects, libraries and executables are provided in dune files following an s-expression syntax.

Generation of binary serialization and deserialization functions from type definitions.

Uses a Mirage CLOCK to write timestamped log messages. It can also log only important messages to the console, while writing all received messages to a ring buffer which is displayed if an exception occurs. If tracing is enabled (via mirage-profile), it also writes each log message to the trace buffer.

Library to perform parallel fold or map taking advantage of multiple core architectures for OCaml programs. Drop-in replacement for these List operations are provided:

• List.map -> parmap

• List.map -> parfold

• List.mapfold -> parmapfold

Also it allows specifying the number of cores to use with the optional parameter ncores.

The OCaml compiler has a bunch of intrinsics for Bigstrings, but they're not widely-known, sometimes misused, and so programs that use Bigstrings are slower than they have to be. And even if a library got that part right and exposed the intrinsics properly, the compiler doesn't have any fast blits between Bigstrings and other string-like types. bigstringaf provides these missing pieces.

Lambda-Term is a cross-platform library for manipulating the terminal. It provides an abstraction for keys, mouse events, colors, as well as a set of widgets to write curses-like applications. The main objective of Lambda-Term is to provide a higher level functional interface to terminal manipulation than, for example, ncurses, by providing a native OCaml interface instead of bindings to a C library.

Library to provide pure OCaml functions to manipulate real file (POSIX like) and filename.

Bindings providing OCaml support for the seminal Fast Fourier Transform library FFTW.

OCamlify creates OCaml source code by including whole files into OCaml string or string list. The code generated can be compiled as a standard OCaml file. It allows embedding external resources as OCaml code.

Cmdliner is a module for the declarative definition of command line interfaces. It provides a simple and compositional mechanism to convert command line arguments to OCaml values and pass them to your functions. The module automatically handles syntax errors, help messages and UNIX man page generation. It supports programs with single or multiple commands and respects most of the POSIX and GNU conventions.

This package provides a library for parsing the contents of OCaml documentation comments, formatted using Odoc syntax, an extension of the language understood by ocamldoc.

Biniou (pronounced "be new" is a binary data format designed for speed, safety, ease of use and backward compatibility as protocols evolve. Biniou is vastly equivalent to JSON in terms of functionality but allows implementations several times faster (4 times faster than yojson), with 25-35% space savings.

This library provides minimal support for Canonical S-expressions. Canonical S-expressions are a binary encoding of S-expressions that is super simple and well suited for communication between programs.

This library only provides a few helpers for simple applications. If you need more advanced support, such as parsing from more fancy input sources, you should consider copying the code of this library given how simple parsing S-expressions in canonical form is.

To avoid a dependency on a particular S-expression library, the only module of this library is parameterised by the type of S-expressions.

React is an OCaml module for functional reactive programming (FRP). It provides support to program with time varying values: declarative events and signals. React doesn't define any primitive event or signal, it lets the client choose the concrete timeline.

The "findlib" library provides a scheme to manage reusable software components (packages), and includes tools that support this scheme. Packages are collections of OCaml modules for which metainformation can be stored. The packages are kept in the file system hierarchy, but with strict directory structure. The library contains functions to look the directory up that stores a package, to query metainformation about a package, and to retrieve dependency information about multiple packages. There is also a tool that allows the user to enter queries on the command-line. In order to simplify compilation and linkage, there are new frontends of the various OCaml compilers that can directly deal with packages.
